This report from Parks Associates examines the growth of the mobile payment industry. A mobile payment is described as a purchase for which a mobile phone is used in the payment process. These payments can be made in-person or remotely. The market for merchants is large as only 30% of U.S. merchants currently accept payment cards. Mobile payment technologies provide a gateway between consumers and merchants, allowing more merchants to accept payment cards and allowing more variety in where consumers can make purchases. Predictions in the growth of the mobile payment market are discussed.
